We know that some people don't think much of the idea of urban farming, in part because it takes up space that could otherwise be used to house people more densely. But what if an urban farm was a) vertical and b) using an otherwise abandoned space?
That's the plan for Alpha Farm, to be built in the Wythenshawe area of Manchester, England. It's going to be constructed in a "fairly generic disused office building," according to the team behind the project, and grow vegetables using aeroponics (which involves spraying roots with nutrient-rich mist), hydroponics (you know how that one works), and aquaponics (basically, hydroponics, except a tank of fish is attached to the system and nutrients come from fish, uh, "activity," as the Alpha Farm team puts it). What now, Ed Glaeser?
